DETAILED DESCRIPTION

Conventional laptop computers generally include a display screen to provide output information to a user, the size of which is determined at least partially for the purpose of optimizing user enjoyment. For example, although many users value laptop computers for their compactness and portability, which may require a reduction in display screen size, users also value display screens which are sufficiently large for the user to comfortably view displayed information. Accordingly, there is an inherent tension in selecting a display screen size for laptop computers having a single screen.

Design tensions associated with the implementation of a single screen may be circumvented with the addition of a second auxiliary screen communicatively coupled to the laptop computer. For example, a second auxiliary screen may be removably coupled to a backplane of a primary laptop screen. In use, a user may slide out or otherwise extend the auxiliary screen from a closed state and position the auxiliary screen in a desired orientation.

Adding a second auxiliary screen coupled to the backplane of the primary laptop screen avoids many of the design tradeoffs associated with increasing the size of a single screen. Modern laptop computer display screens are typically significantly larger in screen area than in screen thickness. Accordingly, whereas increasing the area of a single display screen yields a proportional increase in the amount of information conveyed by the display screen, adding a second auxiliary screen affixed to the backplane of the primary display screen provides approximately twice as much information at the cost of a relatively small increase in thickness. The addition of a second auxiliary screen therefore yields a significant increase in information density (i.e., the amount of information conveyed relative to the physical footprint of the laptop computer) compared to increasing the size of a single primary laptop screen.

Furthermore, in some embodiments, the user may position the auxiliary screen such that the display screen is antiparallel to the primary display screen and parallel to the backplane of the display screen. In this configuration, the auxiliary screen may be configured to function similar to a tablet computer which is capable of displaying output information and capable of receiving input information including inputs from a user's touch, inputs from a stylus, and so forth.

FIG. 1A illustrates a perspective view of a laptop computer 100 in combination with an auxiliary monitor 102 in a closed position according to one embodiment. The auxiliary monitor 102 may be configured to be removably coupled to a backplane 104 of the computer 100. The auxiliary monitor 102 may be further configured to be communicatively coupled to the laptop computer 100 via a wired connection 106.

The laptop computer 100 includes a keyboard portion 101 and a wired communications port 103. The auxiliary monitor 102 includes a display portion 108, a first rail 110 a, a second rail 110 b, and a wired communications port 112. The display portion 108 is generally configured to display information for viewing by a user. In some embodiments, the display portion 108 is configured to receive input information including, for example, touch inputs from a user's finger, inputs from a stylus operated by a user, and so forth.

In the embodiment illustrated by FIG. 1A, the display portion 108 is in a closed position such that a screen of the display portion 108 is not visible to a user. The first rail 110 a and the second rail 110 b are configured to allow the display portion 108 to slide in either direction of at least one dimension. The wired communications port 112 is configured to be coupled to the wired connection 106 to establish communication with the wired communications port 103. For example, the wired communications port 103 and the wired communications port 112 may be configured according to one of several standards, including DisplayPort, Mini DisplayPort, HDMI, VGA, DVI, USB-A, USB-C, Micro-USB, Mini-USB, and so forth. In some embodiments, the wired communications port 103 is configured according to the USB-C standard, the wired communications port 112 is configured according to the USB-A standard, and the wired connection 106 includes a USB-A to USB-C connection standard.

FIG. 1B illustrates a back view of the laptop computer 100 in combination with the auxiliary monitor 102 in a closed position according to an embodiment. FIG. 1C illustrates a front view of the laptop computer 100 in combination with the auxiliary monitor 102 (not visible) in a closed position according to an embodiment. The laptop computer 100 includes a primary screen 105 configured to display output information to a user. FIG. 1D illustrates a side view of the laptop computer 100 in combination with the auxiliary monitor 102 in a closed position according to an embodiment.

As illustrated by the embodiment shown in FIGS. 1B and 1C, the diagonal screen measurement of the auxiliary monitor 102 is smaller than the diagonal screen measurement of the primary screen 105. The addition of the auxiliary monitor 102 therefore does not increase the footprint of the area of the laptop computer 100. Accordingly, when viewed from the perspective of FIG. 1C, the area of the primary screen 105 is not affected by the auxiliary monitor 102. As illustrated by FIG. 1D, the thickness of the auxiliary monitor 102 adds a relatively small increase in total thickness when coupled with the laptop computer 100.

For example, in some embodiments, the auxiliary monitor 102 may have a thickness of approximately 0.34″. The diagonal screen measurement of the display portion 108 may be selected according to the diagonal screen measurement of the laptop computer 100 display screen. For example, for a laptop computer screen having a diagonal screen measurement of approximately 13.3″, the display portion 108 may have a diagonal screen measurement of approximately 12.5″ in some embodiments. It is to be appreciated that the display portion 108 may be manufactured with any diagonal screen measurement desired, and no limitation is meant to be implied by the foregoing values. For example, the display portion 108 could have a diagonal screen measurement which is larger than a diagonal screen measurement of a screen of the laptop computer to which the display portion 108 is attached.

FIG. 2A illustrates a perspective view of the laptop computer 100 in combination with the auxiliary monitor 102 in an “open position” according to an embodiment. According to at least one example, the auxiliary monitor 102 is in an open position when the display portion 108 is at least partially visible to at least one user. For example, the auxiliary monitor 102 may be at least partially visible when the display portion 108 is slid at least partially out from behind the primary screen 105.

FIG. 2B illustrates a back view of the laptop computer 100 in combination with the auxiliary monitor 102 in an open position according to an embodiment. The display portion 108 may be considered to be in a “fully open” position, as defined by the display portion 108 being fully extended in one dimension along the rails 110 a, 110 b. Stated differently, the display portion 108 is in a fully open position when the display portion 108 is incapable of being slid any further along the rails 110 a, 110 b in one direction. In some embodiments, the display portion 108 may be considered to be in a “partially open” position when the display portion 108 is between a closed position and a fully open position and is capable of further extension and retraction in at least one direction.

The auxiliary monitor 102 may be configured to enter a sleep state responsive to determining that the auxiliary monitor 102 is in a particular position. The sleep state may include, for example, implementing a reduced set of functionality, disabling the display portion 108 from receiving or displaying information, and so forth. For example, the auxiliary monitor 102 may be configured to enter the sleep state and disable the display portion 108 from displaying information responsive to determining that the display portion 108 is in a closed position, and may be configured to re-enable the display portion 108 to display information responsive to determining that the display portion 108 has been slid into one of a partially open position and a fully open position.

FIG. 3 illustrates a perspective view of the laptop computer 100 in combination with the auxiliary monitor 102 in an open, “non-parallel” configuration according to an embodiment. According to at least one example, the auxiliary monitor 102 is in a non-parallel configuration when the display portion 108 is rotated to an orientation that is not parallel or antiparallel to the screen of the laptop computer 100. In at least one example, the auxiliary monitor 102 is in a parallel configuration when the display portion 108 is not rotated relative to the closed position, and is parallel to the primary screen 105.

In some embodiments, the display portion 108 may be rotated approximately 90° relative to the parallel configuration towards the primary screen 105. The display portion 108 may be rotated approximately 180° relative to the parallel configuration away from the primary screen 105 such that the display portion 108 is antiparallel to the primary screen 105. In some embodiments, the auxiliary monitor 102 is considered to be in a “tabletized” configuration when the display portion 108 is antiparallel to the primary screen 105.

FIG. 4A illustrates a back perspective view of the laptop computer 100 in combination with the auxiliary monitor 102 in the tabletized configuration according to an embodiment. FIG. 4B illustrates a top view of the laptop computer 100 in combination with the auxiliary monitor 102 in a tabletized configuration according to another embodiment. In some embodiments, the auxiliary monitor 102 is flush with the rails 110 a, 110 b in the tabletized configuration (i.e., the rails 110 a, 110 b and the display portion 108 extend from the backplane 104 by equal distances).

As illustrated by FIGS. 4A and 4B, the display portion 108 is antiparallel with the primary screen 105 in the tabletized configuration. The tabletized configuration may be considered particularly advantageous in various situations, including situations in which the auxiliary monitor 102 is used in a manner similar to a tablet computer. In at least one embodiment, the functionality of the auxiliary monitor 102 does not change regardless of the orientation of the display portion 108. The auxiliary monitor 102 may be capable of receiving input information (for example, from a stylus) and providing output information (for example, displaying a video) in any configuration and orientation. However, users may consider the tabletized configuration to be more advantageous than other configurations for certain tasks, such as writing on the display portion 108 with a stylus, because the tabletized configuration provides an ergonomic and stable working surface for users.

Although FIGS. 4A and 4B illustrate the laptop computer 100 as being in an open configuration (i.e., a configuration in which the primary screen 105 is not anti-parallel with the keyboard portion 101), the auxiliary monitor 102 may also operate in the tabletized configuration when the laptop computer is in a closed configuration (i.e., a configuration in which the primary screen 105 is anti-parallel with the keyboard portion 101).

The laptop computer 100 may be configured to enter a sleep state responsive to detecting that the laptop computer is in a closed configuration. In some embodiments, the laptop computer 100 is configured to implement a reduced set of functionality in the sleep state. In other embodiments, the laptop computer 100 may disable the primary screen 105 from displaying output information in the sleep state. The auxiliary monitor 102 may be capable of operating normally by receiving input information and displaying output information even when the laptop computer 100 is in a sleep state.

The auxiliary monitor 102 will now be described in greater detail with respect to FIGS. 5-7. FIG. 5 illustrates an exploded view of the auxiliary monitor 102 according to an embodiment. The auxiliary monitor 102 generally includes a mounting portion 114, and the display portion 108. The mounting portion 114 includes coupling elements 116 and a mount 118. The display portion 108 includes a front cover 120, a display screen 122, a Printed Circuit Board (PCB) 124, and a back cover 126. In some embodiments, the front cover 120 and the display screen 122 may comprise a single entity, and are identified as separate elements for explanatory purposes only.

The coupling elements 116 are configured to couple the auxiliary monitor 102 to the laptop computer 100, as discussed in greater detail below. The mount 118 is configured to be slidably and rotatably coupled to the display portion 108, as discussed in greater detail below. The front cover 120 and the back cover 126 are configured to encapsulate the display screen 122 to prevent damage to, and displacement of, the display screen 122. The front cover 120 may be constructed of a conductive material that enables a touch input on a first side of the front cover 120 to be sensed by the display screen 122 on the second side of the front cover 120. For example, the front cover 120 may be constructed of a conductive glass material.

The display screen 122 is configured to receive input information, such as touch inputs, and provide output information, such as a video display, as discussed in greater detail below. The display screen 122 may also be configured to receive one or more control signals from the PCB 124. The PCB 124 may be configured to communicate one or more control signals to the display screen 122 depending on a position, orientation, or configuration of the display portion 108. For example, the PCB 124 may communicate a sleep signal to the display screen 122 responsive to determining that the display portion 108 is in a closed position.

In some embodiments, the PCB 124 may be further configured to communicate one or more control signals to the laptop computer 100. For example, the PCB 124 may be configured to receive a first set of one or more signals indicative of a touch input on the display screen 122, and communicate a second set of one or more signals (for example, derived from the first set of one or more signals) to the laptop computer 100.

As discussed above, the back cover 126 is configured to prevent damage to, and displacement of, the display screen 122. The back cover 126 is also configured to interface with the mount 118 to allow the display portion 108 to be slidably connected to the mount 118, as discussed in greater detail below.

The coupling elements 116 will now be described in greater detail. As discussed above, the coupling elements 116 are configured to connect the auxiliary monitor 102 to the laptop computer 100. For example, the coupling elements 116 may be adhesive magnets having an adhesive side and a magnetic side. For example, the adhesive side may include a chemical substance which binds one or more objects together and resists the objects' physical separation, such as glue. The adhesive side may be coupled to the mount 118, and the magnetic side may be configured to be coupled with a corresponding magnetic surface. For example, the laptop computer 100 may be coupled to one or more adhesive magnets each having an adhesive side coupled to the laptop computer 100, and a magnetic side configured to be coupled to a corresponding coupling element of the coupling elements 116.

The implementation of adhesive magnets for the coupling elements 116 allows the auxiliary monitor 102 to be removably coupled to the laptop computer 100. The magnetic strength of the magnets may be selected such that the auxiliary monitor 102 does not become inadvertently decoupled from the laptop computer 100, while allowing a user to decouple the auxiliary monitor 102 from the laptop computer 100 by pulling the auxiliary monitor 102 apart from the laptop computer 100.

In other embodiments, the coupling elements 116 may not be adhesive magnets. For example, the coupling elements 116 may each have an adhesive side and a hook-and-loop side to enable the auxiliary monitor 102 to be removably coupled to the laptop computer 100. In other examples, both sides of the coupling elements 116 may be adhesive. In still other embodiments, the coupling elements 116 may include two or more of the foregoing examples. It is to be appreciated that, although four coupling elements 116 are illustrated, any number of coupling elements may be implemented in other embodiments.

The mount 118 will now be discussed in greater detail. The mount 118 includes the first rail 110 a, the second rail 110 b, and a notch 128. As discussed above, the first rail 110 a and the second rail 110 b are configured to be coupled to the display portion 108 to allow the display portion 108 to slide relative to the mount 118. The notch 128 is a cut-away from the mount 118 to provide the display portion 108 with any clearance necessary to rotate freely. For example, the notch 128 may be as long or longer than the length of the display portion 108 and as wide or wider than the thickness of the display portion 108.

FIG. 6 illustrates the auxiliary monitor 102 from a back perspective view according to an embodiment. As illustrated by FIG. 6, the mount 118 includes a groove 130 in the second rail 110 b to slidably couple with the display portion 108. For example, the display portion 108 may include a protrusion configured to protrude into, and slide along, the groove 130. In some embodiments, the first rail 110 a may include a similar groove (not illustrated) configured to slidably couple with a second protrusion of the display portion 108.

The display screen 122 will now be discussed in greater detail. The display screen 122 may be configured to receive input information and provide output information. For example, in some embodiments, the display screen 122 may be implemented as a tablet computer. To receive input information, the display screen 122 may include a touch-sensitive surface configured to respond to touch inputs from a user's finger, a stylus, and so forth. For example, as discussed above, the front cover 120 may be part of the display screen 122 and may act as a touch-sensitive surface for the display screen 122. To provide output information, the display screen 122 may display information to a user, similar to a computer monitor.

The display screen 122 may also include a wired or wireless communications interface to exchange information with one or more computers. For example, the display screen 122 may include a communications interface to exchange information with the laptop computer 100, such information provided by the laptop computer 100 indicating display information to be output by the display portion 108.

In at least one embodiment, a wired communications interface is embodied by the wired communications port 112. The wired communications port 112 enables the display screen 122 to exchange information with the laptop computer 100 via the wired connection 106. In some embodiments, the display screen 122 may include a wireless communications interface instead of, or in addition to, the wired communication interface. For example, the display screen 122 may include a wireless communications interface configured to enable wireless communication with the laptop computer 100.

In some embodiments, the display screen 122 may include a controller. The controller may be configured to generate one or more control signals to control operation of the display screen 122. For example, the controller may generate one or more control signals to display output information on the display screen 122 in response to input information received by the display screen 122 from, for example, the PCB 124. In some embodiments, the controller operates in conjunction with the laptop computer 100. In other embodiments, the controller operates without communicating with the laptop computer 100. In still other embodiments, the display screen 122 may not include a controller, and may instead receive control signals solely from at least one of the laptop computer 100 and the PCB 124.

The back cover 126 will now be discussed in greater detail. The back cover 126 is configured to be coupled to the display screen 122, and includes a first hinge 132 a and a second hinge 132 b configured to couple to the mount 118. The hinges 132 a, 132 b may be configured to protrude into the rails 110 a, 110 b, respectively, of the mount 118. In some embodiments, the hinges 132 a, 132 b may be configured to slide in direct contact with the rails 110 a, 110 b.

FIG. 7 illustrates a side cross-sectional view of the auxiliary monitor 102 according to an embodiment. The second hinge 134 b may protrude into the groove 130 of the second rail 110 b, and the first hinge 134 a may protrude into a similar groove in the first rail 110 a. The hinges 132 a, 132 b may be configured such that, when the display portion 108 is in a fully open position (i.e., the display portion 108 is slid as much as possible in one direction), the display portion 108 is capable of being rotated about the hinges 132 a, 132 b to a desired orientation.

Alternative coupling mechanisms between the back cover 126 and the mount 118 are intended to be within the scope of this disclosure. Although the foregoing description notes that the hinges 132 a, 132 b may be configured to slide in direct contact with the rails 110 a, 110 b, in alternate embodiments, other sliding mechanisms may be implemented. For example, ball bearings may be implemented to facilitate sliding between the hinges 132 a, 132 b and the rails 110 a, 110 b. In still other examples, roller mechanisms may be implemented to facilitate sliding between the hinges 132 a, 132 b and the rails 110 a, 110 b. As discussed in greater detail below, in alternate embodiments, alternate implementations of the hinges 132 a, 132 b and the rails 110 a, 110 b may be within the scope of this disclosure.

An auxiliary monitor has been disclosed. The auxiliary monitor is capable of receiving input information from a user and providing output information to a user. The auxiliary monitor increases the physical footprint of an associated laptop computer by a marginal amount, while providing significant benefits in the amount of information that can be exchanged between the user and the combination of the laptop computer and the auxiliary monitor. The auxiliary monitor also expands the functionality of the laptop computer, such as by allowing the auxiliary monitor to be used in a similar manner as a tablet computer.

No limitation of the auxiliary monitor is meant to be implied by the word “auxiliary.” The auxiliary monitor may be used even when the laptop computer is in an idle or sleep mode such that the auxiliary monitor is the only active monitor. For example, the laptop computer may be closed while the user continues to use the auxiliary monitor. Furthermore, no limitation is meant to be implied by the word “monitor.” Although some embodiments of the auxiliary monitor are capable of displaying output information, some embodiments of the auxiliary monitor are also capable of receiving input information from a user, such as via touch inputs. In alternate embodiments, the auxiliary monitor is only capable of displaying information to a user, and receiving information the laptop computer, but incapable of receiving touch inputs from a user.

The auxiliary monitor may be any size and may have any desired dimensions. Although some of the foregoing embodiments illustrate the auxiliary monitor as having a smaller screen area than that of the corresponding laptop computer, in alternate embodiments, the auxiliary monitor may have a screen area that is larger than that of the corresponding laptop computer.

In some embodiments, the auxiliary monitor is communicatively coupled to the laptop computer via a wired connection. In some implementations, a user may desire the wired connection to be on one side or the other of the laptop computer. To reverse the auxiliary monitor, the auxiliary monitor can be decoupled from the backplane of the laptop computer, rotated 180° about a vector normal to the backplane of the laptop computer, and re-coupled to the backplane of the laptop computer, effectively moving the wired connection between the left and right sides of the laptop computer for ease of use by a user.

As discussed above, an auxiliary monitor may be slidably and rotatably coupled to a mount coupled to a primary display. For example, the auxiliary monitor may be able to slide relative to the mount along at least one rail, and may be able to rotate relative to the mount about at least one hinge. One embodiment is discussed above with respect to the hinges 132 a, 132 b and the rails 110 a, 110 b.

FIG. 8 illustrates a perspective view of an auxiliary display system 800 according to another embodiment. The auxiliary display system 800 includes a mount 802, an auxiliary display 804, and a hinge assembly 806. The mount 802 is configured to be coupled to a primary surface, such as a backplane of a laptop computer, and is configured to be slidably coupled to the hinge assembly 806. The auxiliary display 804 is configured to be coupled to the hinge assembly 806. The hinge assembly 806 is configured to be slidably and rotatably coupled to the mount 802. For example, and as discussed in greater detail below, the mount 802 may include a track 807 configured to engage with the hinge assembly 806.

An embodiment of the hinge assembly 806 will now be discussed with respect to FIGS. 9A-9C. FIG. 9A is a side view of the hinge assembly 806 according to an embodiment. FIG. 9B is a front view of the hinge assembly 806 according to an embodiment. FIG. 9C is a perspective view of the hinge assembly 806 according to an embodiment.

The hinge assembly 806 includes a carriage head 808, a carriage head mount 810, and a mounting block 812. The carriage head 808 is configured to be slidably coupled to a mount, such as the mount 802. For example, the carriage head 808 may be configured to be coupled to the track 807 of the mount 802. More specifically, a protrusion 809 of the carriage head 808 may be configured to protrude into the track 807, as discussed in greater detail below.

The carriage head mount 810 is configured to be coupled to the carriage head 808, and is configured to be rotatably coupled to the mounting block 812. For example, and with reference to FIG. 9A, the carriage head mount 810 may be configured to rotate about the Y-axis. The mounting block 812 is configured to be rotatably coupled to the carriage head mount 810, and is configured to be coupled to a display portion. For example, the mounting block 812 may be configured to be coupled to the auxiliary display 804. In some embodiments, in which the mounting block 812 is coupled to the auxiliary display 804, the carriage head 808 and the carriage head mount 810 may enable the auxiliary display 804 to be slidably and rotatably coupled, respectively, to the mount 802.

In at least one embodiment, the carriage head 808 may be configured to engage the track 807 at four points of contact identified below. Maximizing a number of points of contact between the carriage head 808 and the track 807 may distribute mechanical stress across a greater area of the carriage head 808 and the track 807, thereby decreasing an amount of mechanical stress placed on any one point of either the carriage head 808 or the track 807. Decreasing the amount of mechanical stress placed on any one point of either the carriage head 808 or the track 807 may increase the longevity of the carriage head 808 and/or the track 807.

For example, and with reference to FIG. 9C, the carriage head 808 includes a first side 816, a second side 818, a third side 820, a fourth side 822, a fifth side 824, a sixth side 826, and a stem portion 828. The first side 816 is perpendicularly connected to the second side 818 at a first vertex, and is perpendicularly connected to the sixth side 826 at a second vertex. The second side 818 is perpendicularly connected to the first side 816 at a first vertex, and is perpendicularly connected to the third side 820 at a second vertex. The third side 820 is perpendicularly connected to the second side 818 at a first vertex, and is perpendicularly connected to the fourth side 822 at a second vertex.

The fourth side 822 is perpendicularly connected to the third side 820 at a first vertex, and is perpendicularly connected to the fifth side 824 at a second vertex. The fifth side 824 is perpendicularly connected to the fourth side 822 at a first vertex, and is perpendicularly coupled to the sixth side 826 at a second vertex. The sixth side 826 is perpendicularly connected to the first side 816 at a first vertex, and is perpendicularly coupled to the fifth side 824 at a second vertex. The stem portion 828 is coupled to, and extends from, the fifth side 824.

As discussed above, in at least one embodiment, the carriage head 808 is configured to engage the track 807 at four points of contact. FIG. 10 illustrates a perspective view of the hinge assembly 806 coupled to the track 807 according to an embodiment. For clarity of illustration, the sides 816-826 are not labeled. As illustrated by FIG. 10, the carriage head 808 of the hinge assembly 806 is configured to contact the track 807 at the first side 816, the second side 818, the third side 820, and the fourth side 822. The protrusion 809 of the carriage head 808 formed by the first side 816, the second side 818, and the third side 820 is configured to protrude into the track 807. The fourth side 822 of the carriage head 808 contacts a top surface 830 of the track 807.

FIG. 11 illustrates a side view of a portion of the carriage head 808 according to an embodiment. The carriage head 808 includes the protrusion 809. The protrusion 809 includes a first track engagement member 848 and a second track engagement member 850. The protrusion 809 has a length measurement 852, the first track engagement member 848 has a length measurement 854, and the second track engagement member 850 has a length measurement 856.

In one embodiment, the first track engagement member 848 may be spaced apart from the second track engagement member 850. For example, the length measurement 852 of the protrusion 809 may be approximately 1.10 inches, the length measurement 854 of the first track engagement member 848 may be approximately 0.15 inches, and the length measurement 856 of the second track engagement member 850 may be approximately 0.31 inches. Accordingly, a space of approximately 0.64 inches may exist between the first track engagement member 848 and the second tack engagement member 850.

In at least one embodiment, the protrusion 809 is configured having a length sufficient to satisfy at least two functions. First, in some embodiments, the auxiliary display system 800 may include two tracks (for example, similar to the track 807) attached to the mount 802. For example, the auxiliary display system 800 may include a track at a top side of the mount 802 and a bottom side of the mount 802, each of which is configured to be coupled to a respective hinge assembly. In some embodiments, it may be advantageous for the two respective hinge assemblies to begin sliding relative to the mount 802 simultaneously, which may be difficult where an engagement length of the respective hinge assemblies are relatively short. Accordingly, a length of the protrusions of the hinge assemblies (for example, the length measurement 852 of the protrusion 809) are selected to be long enough to prevent misalignment of the top and bottom hinge assemblies included in certain embodiments.

Second, in some embodiments, it is to be appreciated that an auxiliary display (for example, the auxiliary display 804) may be fully extended relative to a primary display connected to the auxiliary display via a mount (for example, the mount 802). As the auxiliary display is extended, a moment may be created about an edge of the primary display, where the moment increases as the auxiliary display extends further. It may be advantageous to prevent the auxiliary display from being extended far enough to cause the primary display to tip over about the edge of the primary display. Accordingly, the length of a protrusion (for example, the length measurement 852 of the protrusion 809) may be selected such that the auxiliary display (for example, the auxiliary display 804) does not cause a primary display to tip over due to the moment generated by the auxiliary display.

In some embodiments, it may be advantageous for the auxiliary display 804 to lock into place when fully extended. Locking into place may include a configuration wherein the auxiliary display 804 is not easily slidable about the track 807, but which may be easily unlocked by a user. To provide a locking mechanism in certain embodiments, protrusion the first track engagement member 848 and the second track engagement member 850 may be configured to accommodate a detent. For example, the first track engagement member 848 and the second track engagement member 850 may be positioned to provide a space between the members 848, 850 which may receive the detent. The detent may resist sliding of the auxiliary display 804 relative to the track 807 below a minimum amount of force applied to the auxiliary display 804 in the direction which the auxiliary display 804 is configured to slide. For example, the detent may extend between the protrusion first track engagement member 848 and the second track engagement member 850 when the auxiliary display 804 is fully extended to resist sliding of the auxiliary display 804. However, if a minimum amount of force is applied to the auxiliary display 804 in the direction which the auxiliary display 804 is configured to slide, at least one of the first track engagement member 848 and the second track engagement member 850 is configured to exert a force on the detent to remove the detent from the space between the members 848, 850, thereby unlocking the auxiliary display 804.

FIG. 12 illustrates an exploded view of the hinge assembly 806 according to an embodiment. As discussed above, the hinge assembly 806 includes the carriage head 808, the carriage mount 810, and the mounting block 812. The carriage head 808 includes openings 832 respectively configured to receive a fastener, as discussed in greater detail below. The carriage mount 810 includes openings 834 respectively configured to receive a fastener, as discussed in greater detail below. The carriage mount 810 further includes a chamfered protrusion 836 configured to be coupled to the mounting block 812.

The mounting block 812 includes openings 838 respectively configured to receive a fastener (not illustrated). For example, the openings 838 may be configured to receive a fastener to couple the mounting block 812 to a display portion. For example, the openings 838 may be configured to receive fasteners to couple the mounting block 812 to the auxiliary display 804.

In at least one embodiment, the carriage head 808 may be configured to be coupled to the carriage mount 810 by fasteners 840. For example, the fasteners 840 may be rivets respectively configured to be inserted into one of the openings 832 and one of the openings 834. In one embodiment, the fasteners 840 may include two rivets, the openings 832 may include two openings, and the openings 834 may include two openings.

In at least one embodiment, the carriage mount 810 is configured to be coupled to the mounting block 812 via the chamfered protrusion 836. For example, the chamfered protrusion 836 may be configured to be inserted through one or more washers 842 and a coupling nut 844. The coupling nut 844 may be configured to be coupled to an end of the chamfered protrusion 836. For example, the chamfered protrusion 836 may be threaded such that the coupling nut 844 may be coupled to the chamfered protrusion 836.

The one or more washers 842 are configured to distribute a load applied by the coupling nut 844. For example, in one embodiment, the chamfered protrusion 836 is configured to pass through an opening 846 in the mounting block 812, the one or more washers 842, and the coupling nut 844. The one or more washers 842 may distribute the load which would otherwise be applied by the coupling nut 844 in direct contact with the mounting block 812.

In one embodiment, the carriage head 808 is manufactured from 17-4 stainless steel. For example, the carriage head 808 may be manufactured from 17-4 stainless steel using metal injection molding. In some embodiments, the carriage head mount 810 and the mounting block 812 may be manufactured from 1144 steel alloy. For example, 1144 steel alloy may be advantageous due to its high stress-resistance. The carriage head mount 810 and the mounting block 812 may be manufactured using metal injection molding.
